Ski gloves, Tinsulate insulation 40g, 3M for $5 (one size fit all)
Went snooping around looking for something cheap (there is no gear in this world that would improve my performance anyway :)) Couldn't find any and asked so one of the employees went "to check at the back" and brought out the whole pack. As you can see in the pic tags say $9.48 but once scanned that turns to $5.
Yet to be tested though :)
2 Kilos of Nutella? That's going to last a while…
